The purpose of this study was to investigate the effects of aliphatic sodium butyrate on some blood parameters and growth factors in carp fingerling with an average weight of 10 g. This experiment was conducted for 8 weeks by using four different diets with three replications including: control (without supplement) and three levels of sodium butyrate (0.25, 0.5 and 1%). Feeding was performed for 2 months daily 2 times 3% of the body weight of the fish and were taken biometric 2 times in a month. At the end, blood parameters (including the number of red blood cells, white blood cell count and fractional count, hematocrit and hemoglobin), and growth factors (final weight, specific growth factor, feed conversion ratio and consumable food intake) were evaluated between the experimental groups. This experiment was done in a completely randomized design. Data analysis was performed using SPSS and Excel software packages. Finally, there was no significant difference in final weight, specific growth factor, feed conversion ratio and food intake between experimental groups. The results of this study showed that sodium butyrate had no effect on the number of red blood cells, hematocrit, hemoglobin, mean corpuscular vein (MCV), moderate hemoglobin (MCH), and moderate hemoglobin concentration (MCHC). There was also a significant difference between the levels of white blood cells between the levels of 0.25% and 1% in the control group. There was no significant difference between the levels of 0.5% and the control group. The results of this experiment showed that the addition of sodium butyrate to carp diet did not affect the growth and blood factors of this fish, but the white blood cell count decreased by 0.25% and 1%.
